Short Description:

Methyl cellulose CAS 9004-67-5
Methyl cellulose, also known as cellulose methyl ether, abbreviated as MC (short for MethylCellulose), is a long-chain substitute for cellulose. The average molecular weight of methyl cellulose is 10000 to 220000, and it is a white powder or fibrous substance at room temperature. It is non-toxic, non irritating, and non allergenic, with an apparent relative density of 0.35 to 0.55 (true relative density of 1.26 to 1.30).
Swelling in water to form a semi transparent viscous colloidal solution, neutral to litmus, insoluble in ethanol, ether, and chloroform, soluble in glacial acetic acid. It is resistant to acid, alkali, microorganisms, heat, light, and is not affected by oil and grease, but it will burn when it reaches the ignition point.

Methyl cellulose is widely used in the construction industry, such as as as an adhesive for cement, mortar, joint debonding, etc. Used as a film-forming agent and adhesive in the cosmetics, pharmaceutical, and food industries.
It is also used as a sizing agent for textile printing and dyeing, a dispersant for synthetic resins, a film-forming agent for coatings, and a thickener. Alkali cellulose is prepared from pulp, which is then reacted with chloromethane or dimethyl sulfate in an autoclave and refined with warm water.
